By Bronwyn Thompson March 01, 2023 An oral or nasal spray delivering peptides to the brain may be able to halt neurodegeneration Depositphotos Scientists have discovered a novel way to halt nerve cell death in the most common forms of motor neuron disease and frontotemporal dementia, which could transform how these neurodegenerative conditions are treated....
Frontotemporal dementia (FTD) is a group of disorders characterized by a progressive degeneration of nerve cells in the frontal lobe or the brain regions underneath the ears. At the Boston University Alzheimer’s Disease Research Center, Andrew Budson, a cognitive and behavioral neurologist and cognitive neuroscientist, studies dementia, including FTD. An expert on memory in people with Alzheimer’s disease and other...

Credit: Tu Yiheng A research team led by Dr. Tu Yiheng from the Institute of Psychology of the Chinese Academy of Sciences has found that people with chronic pain in multiple parts of the body had a higher risk of dementia...
by Erin Fox, University of Michigan Credit: Pixabay/CC0 Public Domain Dementia affects millions of Americans—including nearly one in 10 adults over age 65. While the causes of different dementias vary, a 2020 report from a Lancet commission identified several modifiable risk factors that together account for around 40% of dementia worldwide.
